Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 48,492,451, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 48,492,451 | |
| -1 | -48,492,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,492,451.
Example:
1 x 48,492,451 = 48,492,451
and
-1 x -48,492,451 = 48,492,451
Notice both answers equal 48,492,451
With that explanation out of the way, let's continue. Next, we take the number 48,492,451 and divide it by 2:
48,492,451 ÷ 2 = 24,246,225.5
If the quotient is a whole number, then 2 and 24,246,225.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 48,492,451 | |
| -1 | -48,492,451 |
Now, we try dividing 48,492,451 by 3:
48,492,451 ÷ 3 = 16,164,150.3333
If the quotient is a whole number, then 3 and 16,164,150.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 48,492,451 | |
| -1 | -48,492,451 |
Let's try dividing by 4:
48,492,451 ÷ 4 = 12,123,112.75
If the quotient is a whole number, then 4 and 12,123,112.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 48,492,451 | |
| -1 | 48,492,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 277 | 281 | 623 | 1,939 | 1,967 | 24,653 | 25,009 | 77,837 | 172,571 | 175,063 | 544,859 | 6,927,493 | 48,492,451 |
| -1 | -7 | -89 | -277 | -281 | -623 | -1,939 | -1,967 | -24,653 | -25,009 | -77,837 | -172,571 | -175,063 | -544,859 | -6,927,493 | -48,492,451 |
